Guess How Many Puppies

If you were paying attention, you'll have noticed that there was no "Guess How Many Puppies" contest for Phoenix. I just didn't get my act together in time before the ultrasound. Then I considered just having a "Guess when they'll arrive" contest, but it was too much like work...!! However, a bit of anticipation was wanting when Phoenix went into labour - the sense of just waiting on tenterhooks to see who would win...

So we're having one for Harmony. 
Here are the rules: Send me your guess including (1) how mny puppies you think Harmony will have, and (2) the date and time of birth of the first pup (to determine a winner since lots of people guess the same number). Whoever has the right number of pups and is closest to the actual date/time of arrival of pUPPY #1 wins a $10 Timmy's card. 

Harmony

 Harmony ovulated on 15 April, so nine weeks later would put it at 17 June. A dam can give birth within 3 days, plus or minus, of the due date. We've usually found them to be 1-4 days in advance. Don't think I've have a dam go later. (If you were that round and heavy, would you?) And most of our girls (with the exception of Topaz) prefer odd numbers. Out of 13 litters, we've had 10 born on odd-numbered days. The most popular time of day is between about 3 and 11pm. We've had one litter born around 4-6am, and a few as early as 2-2:30, but nothing outside those hours. The most popular number is six. (We've had one litter of 2; two litters of 4; three litters of 5; six litters of 6, and one litter of 8.)

So guess away!! Guesses must be submitted by midnight of the day on which Harmony has her ultrasound, which isn't scheduled yet but is likely to be around 16-18 May.
